Safety performance evaluation of Indian organizations using data envelopment analysis

An integrated approach for economic evaluation of environmental and health costs of occupational diseases in the oil industry

The health sector is one of the components of development, social welfare and economic growth. The purpose of this study was to develop an economic evaluation model of the environmental and health costs of occupational diseases by hybrid approach. To achieve the study goal, a taxonomy of economic evaluation model of the environmental and health costs of occupational diseases has been developed. The Delphi method was used to identify health and environmental criteria and the analytic network process (ANP) method was used to weigh the sub-criteria. Finally, health and environmental cost were estimated based on the available information. Naft Subspecialty Hospital in Tehran, Iran (NSHT), was selected as the place of case study. In this study, eight and eleven sub-criteria were identified in the health and environmental sector, respectively. The ANP results indicated that the medicine and medical equipment cost criteria with a weight of 0.312 in the Medical sector, and the special and infectious waste cost criteria with a weight of 0.085 in the environmental sector were the most significant cost criteria in NSHT. Furthermore, the parametric model findings indicated that 99.84 and 0.16% of the total costs are associated with health and environmental costs, respectively. The findings indicated that 61.3% of the costs of the health sector were associated with the two sectors of medicine and medical equipment and the cost-of-service personnel, and 91.7% of the costs of the environmental sector are associated with wastewater treatment and the cost of electricity consumption. This study tried to present a quantitative model of the health and environmental costs of NSHT. Implemention of this integrated model can be a practical and effective step in allocating resources and prioritize interventions.

Transportation extended wastes and road haulage efficiency

Purpose

Although recent research acknowledges the importance of reducing the inefficient activities from road transportation, there is still a missing link in literature of how transportation extended wastes impact road haulers efficiency. The purpose of this paper is to investigate the relationship between waste reduction practices (WRP) and fleet operational efficiency (FOE) in road hauler firms.

Design/methodology/approach

A theoretical model was developed to assess this relationship. The authors test the model with a sample from logistics companies providing road haulage services in the Middle East, providing a contribution to extant literature from a different setting.

Findings

Results suggest that WRP have a positive and significant impact on FOE. A valuable scale for the measurement of operational efficiency was developed and validated, representing an index toward the most efficient organization.

Practical implications

The findings of this study serves as a tool for shippers to benchmark the efficiency levels of their motor carrier service providers against each other, considering that segmentation is a relevant issue to understand the choice in favor of a given provider to the detriment of another. Furthermore, road haulers can use the efficiency measurements as a basis for establishing future action plans to adopt waste reduction practices.

Originality/value

The research deals with a newly emerging stream of research on linking waste practices to road transport. The authors contribute to this developing body of research through filling a gap in the link between waste and road transport operational performance. The research is also different from recent literature in that the authors provide insights from a larger population, unlike other similar studies who used VSM and studied only a particular case. Thus, the work is important to generalize the findings, especially that the authors provide a perspective from a non-western perspective.

Performance evaluation and prioritization of organizations based on knowledge management and safety management approaches using DEA

Purpose

The purpose of this paper is to propose a method for performance assessment of organizations based on integrated approach of knowledge management and safety management using data envelopment analysis, and the proposed model is then applied in the car industry in Isfahan province to be checked. Therefore, deficiencies can be highlighted and possible strategies can be evolved to improve the performance.

Design/methodology/approach

As data envelopment analysis is a robust mathematical tool, it has been used to evaluate organizational performance. For discovering the organizational performance of knowledge management and safety management by data envelopment analysis (DEA), the first step is to specify proper criteria. To this end, in this method, the indices in both approaches of knowledge management and safety management were identified. Then, inputs and outputs were specified. Knowledge management and safety management were determined as input indices, and customer satisfaction and accident indicators were the output indices. It is noteworthy that each output index was used one time. In the next stage, performance of organizations was assessed based on both determined approaches and via data envelopment analysis. Finally, the organizations were ranked.

Findings

The suggested method was implemented in the car industry in the Isfahan province. The obtained results disclosed that among 12 decision-making units, 4 units are efficient when customer satisfaction is the output and 5 units are efficient when accidents indices are the output. In ranking with customer satisfaction as the output, Sepahan Atlas Pump Company was ranked first via super efficiency method, data envelopment analysis and similarity to ideal solution. In ranking with accidents as the output, Sepahan Atlas Pump Company ranked first via strong efficiency method and Sanatgar Company ranked first via data envelopment analysis and similarity to ideal solution.

Originality/value

Knowledge has been recognized as one of the valuable resources, and knowledge management would greatly effect improvement of job quality. Knowledge level increase is led by better performance and less errors. Consequently, it can enhance the organizational health and safety. There are some studies which have been conducted on safety management or knowledge management performance analysis. The organizational performance evaluation based on integrated approach of knowledge management and safety management is an important issue which is less considered in theory and practice. Thus, the authors have proposed a method which is able to evaluate the organization based on this integrated approach with functional indices, which resulted in accurate results, and finally, ranking can show the organization status to determine proper strategies.

Benchmarking the performance indicators of Indian Railway container business using data envelopment analysis

Purpose

– Indian Railways being sole government organization for infrastructure, operations and regulatory functions entered for competition in the container segment in January 2006 through private-public participation for customer-centric competitiveness to break monopolistic control of Container Corporation of India (CONCOR) introducing limited licensing policy. The purpose of this research work is to carry out benchmarking the performance indicators in Indian Railway container business and select private players.

Design/methodology/approach

– A case study has been conducted employing data envelopment analysis (DEA) methodology on secondary data of container terminals of CONCOR, Adani and Gateway logistics. Data from the year 1995-1996 till 2010-2011 have been used for performance evaluation within CONCOR itself and comparative analysis for all three organizations from 2005-2006 till 2010-2011.

Findings

– The exercise identified efficiency trends fluctuating between 87.5 and 100 percent within CONCOR owing to haphazard infrastructure developed while comparison with private players showed 38.31-77.59 percent efficiency fluctuation concurrent to licensing policy norms.

Research limitations/implications

– The reliability of data provided by the selected operators for needful research is merely on the information and available sources.

Originality/value

– The study enables the reader to gain some valuable insights from a managerial perspective by the use of DEA methodologies so as to formulate strategies to foster better performance.
